Charles Darwin in the Galapagos Islands
About Charles Darwin
Charles Darwin was twenty years old when he boarded the HMS Beagle to the Galapagos Islands in 1831. Three decades later, he published his theory of evolution. It is considered one of the most revolutionary ideas of science. However, Professor Louis Bouroune says this: "Evolutionism is a fairytale for grown-ups. This theory has helped nothing in the progress of science. It is useless." Darwin's discovery on the islands has attracted the attention of many because of the fascinating things that were discovered.
Natural selection is the process where organisms that adapt to their environment tend to survive and produce more offspring. It is however only a theory, like evolution. It is also a key mechanism to the belief of evolution. Although often misunderstood, it is generally simple. Imagine a population of beetles that live in the forest, where the soil is very dark. Some beetles are green, while some are brown. Since green beetles do not produce as often, and are unable to blend in as well as the brown beetles, it is harder for them to survive than the brown beetles. The surviving brown beetles produce brown baby beetles because the trait has a genetic basis. In tern, the more beneficial trait(brown coloration) becomes more common in the beetle population. If this process were to continue, all beetles in the beetle population would eventually be brown.
Darwin's finches are an excellent example that shows the was in which a species's genes have adapted. They have adapted to ensure the species's long term survival. Their beaks have evolved over time for their function; and example would be a finch with a large, thick beak that is used to eat buds and fruit. Darwin collected some of these finches, and it is stated that these finches are an important key to the development of his idea of evolution, and are used in many textbooks today.
